Title: Data discriminator
Inventor: SHIMADA TOSHIYUKI
IPC: G11B20/10
Filed: 1984-02-27
Abstract: PURPOSE:To reduce a pulse code reproduction error with simple constitution even in a modulation system which contains a large number of low band frequency components, by obtaining a differential of the reproduction outputs. CONSTITUTION:A reproduction output signal is supplied to a differential A/D converter 8, and a differential signal of the reproduction output signal is delivered to a transversal filter 5 after A/D conversion. This A/D converted signal undergoes the equalization of waveform through the filter 5 and is delivered to an extreme point phase detector 13. The detector 13 has an amplitude comparison level Xref and works only when Xi<=Xref is satisfied to an input signal series Xi. Then the detector 13 delivers the position information on the maximum or minimum value of the Xi in the form of the phase information to a synchronizing clock signal together with the extreme point phase signal. This phase signal is delivered to a data reproducer 7, and the reproducer 7 reproduces a pulse code. In such a way, the pulse code is detected out of the reproduction output signal by the differential detection. Thus the reproduction error of the pulse code can be reduced without using substantially the low band frequency component of the reproduction output signal.

Filed: 1987-02-18
Abstract: PURPOSE:To attain a purpose only by depressing a key on a left side or a right side obscurely without identifying a specific key even when input is the one of a bit of binary information, by classifying a depressed key to the left side or the right side. CONSTITUTION:When the key on a keyboard 10 is depressed, a key code 30 is generated, and it is sent to a right and left side deciding mechanism 2. The left and right side deciding mechanism 2 decides on which side, left or right, the key corresponding to the key code 30 is positioned on the keyboard by collating a sent key code 30 with a table 1, and checking a corresponding left or right identification code. A conversion mechanism 3 converts key input to either the binary information based on an obtained result. For example, if a depressed key is positioned on the left side, that is, if the corresponding left or right identification code 40 is a code L on the left, a character on a screen is moved to the left, and it is positioned on the right side, the character is moved to the right.
